Slope stability and seismic dislocations

Abstract

Various distortions of the Earth's surface can appear in the pleistoseiste area during earthquakes more than 7 intensity, i. e. fissures, scarps, rockfalls, landslides ertc. Formation and size of the distortions are controlled by landforms and their elements position with view to seismic ray exit direction, depth of dissection and slope steepness. Slope stability is influenced by tectonic structure, composition and state of the rocks (lithology, weathering, fissures) as well as by hydro geological conditions.
